Dynamic DNS support..

I have RB450, I can’t find how to configure dynamic DNS support.
Is this supported by default, or I should use scripting ?

tnx..

Scripting it is. Thankfully there are already some nice scripts out there:

I really like DNS-O-Matic. It works with many different Dynamic DNS providers. http://www.dnsomatic.com/
